Description
Technical field
The utility model relates to integrating sphere field, especially a kind of color measuring device of integrating sphere.
Background technique
Integrating sphere is a kind of sphere of cavity, and light after multiple reflections and diffusion, realizes light in ball interior
Uniformly it is scattered in inside integrating sphere.Therefore, the primary condition of product of ideal bulb separation includes the following: (1) the interior table of integrating sphere
Face is complete geometry spherical surface；(2) radius of every bit is identical on integrating sphere inner surface；(3) integrating sphere inner wall is uniformly unrestrained anti-
Penetrate face；(4) integrating sphere inner wall is to the incident ray of various wavelength diffusing reflection having the same ratio；(5) not any in integrating sphere
Object；(6) light source is considered as only shining without abstract light source in kind.
But above-mentioned primary condition is the ideal conditions of integrating sphere, is necessarily required in practical applications to integrating sphere aperture
(or cracking) or in inside installation screen, so that integrating sphere deviates from the primary condition of product of ideal bulb separation.Aperture is for being arranged light
Line entrance port, detection mouth or other component, the area of aperture and the ratio of integrating sphere inner surface are known as percent opening, and percent opening is got over
Small, the inner surface closer to product of ideal bulb separation is this primary condition of full geometry spherical surface；By the same light source of integrating sphere, detector
When etc. organizing together, what cannot be avoided installs screen inside integrating sphere, the screen installed inside integrating sphere or other
Component is fewer, just without this primary condition of any object in the integrating sphere of product of ideal bulb separation.
The utility model patent of China ZL 201621159676.6, entitled " monochromatic light road spectrophotometric color measurement instrument " is (following
Referred to as " No. 766 patents ") a kind of monochromatic light road spectrophotometric color measurement instrument of integrating sphere is disclosed, there is gear inside the integrating sphere of No. 766 patents
Tabula rasa and plectrum, wherein light barrier is fixed, and plectrum passes through the into or out integrating sphere in gap on integrating sphere, gear
The light that tabula rasa is used to block light source sending is emitted directly toward measured object surface.
No. 766 patents and the primary condition of product of ideal bulb separation are compared, it has been found that kept off present in No. 766 patents
Tabula rasa so that the integrating sphere of No. 766 patents in product of ideal bulb separation without this primary condition of any object deviate it is larger；Together
When, No. 766 patents are cracked on integrating sphere, the percent opening of integrating sphere are increased, so that the integrating sphere and reason of No. 766 patents
Think that integrating sphere inner surface is that complete this primary condition of geometry spherical surface deviation is larger.On the one hand the light barrier of No. 766 patents hinders
The light for blocking light source sending is emitted directly toward measured object surface, has on the other hand also stopped the reflection of other light integrating sphere Nei
And diffusion, the light destroyed in integrating sphere is uniformly scattered to the inside of integrating sphere；It cracks on the integrating sphere of No. 766 patents,
The light destroyed in integrating sphere is uniformly scattered to the inside of integrating sphere, it is also possible to extraneous light be caused to be injected into integrating sphere
Or light causes to measure the unstable of light intensity from gap leakage integrating sphere in integrating sphere.
For can be applied to the product of No. 766 patents and the integrating sphere of other products, need according to product of ideal bulb separation
Primary condition, it is further to reduce percent opening and reduce the object in integrating sphere, so that integrating sphere inside is to the equal of light
Even scattering, and guarantee the stabilization of integrating sphere internal light intensity.Meanwhile the fixed gear inside the integrating sphere of No. 766 patents
Tabula rasa or crack can all increase the difficulty and cost of manufacture integrating sphere；In addition, being so that plectrum passes through the into and out product in gap
Bulb separation also will increase the difficulty and cost of integrating sphere assembling.Therefore, in the color measuring device of integrating sphere field, especially integrating sphere
Field needs the colour examining of the integrating sphere and integrating sphere of a kind of simple, easy to assembly, close to product of ideal bulb separation the primary condition of structure
Device.
